I agree. I can't think of a good reason to weld letters on a functional gun barrel.

Re: 6061 Corner Detail

Your left image, inside corner to inside corner, is an excellent way to approach this. I grind the knife edge flat on steel too. The weld is much easier to make uniform that way. When making any outside corner, I use inside corner to inside corner, or a little overlap. This saves from having to beve...

Re: Feet First Foray into MIGing 0.190" 6061

Opinion, 140 amps is very small for the thickness you want to weld.

Aluminum mig is a spray arc transfer.
Adjust until you hear the fine humming of spray instead of the crackle of short circuit transfer.

Just base it on the video, it's pretty crude looking but should get it done for you.

Re: slag

Yep, 6011 and 6010 share that characteristic.

Scraping the weld with the chipping hammer is often all that is needed.

Wire wheel on angle grinder works good too.

Re: Modifications on stick welding machines

Since your machine uses a movable shunt to control the amps, I don't see how you would change that to a rheostat style machine?

DC+ tig works pretty good for thin aluminum - not super great or anything, but does the job.

Re: WTF am i doing wrong: TIG mild steel

You did a lot wrong. Not cleaning correctly is a mistake. Buying "mild steel oxy filler rod" for tig is an obvious one :D RG45 rods are not made like tig rods. With good clean steel the weld will often be very gray. Same for coat hangers. In 70s-2 and 70s-6 tig rods, the -2 and -6 are sili...

I've never seen issues with carbon steel soaking up contaminants. That's usually something you find in cast parts. You are aware carbon steel is porous, right? An oil pan will soak up oil, road grime and other “weld contaminating” impurities irrespective of it being cast, forged, billet or hydro fo...

Re: vertical 7018 stringers

I've found a quick pass vertical down with 6010 or 6011 seals up the piece with very little fuss.

A vertical up pass with 3/32" 7018 works fine after, if needed.

Re: too much weld

Wire feed speed is the amperage.

Volts adjusts the puddle profile and arc length for self shielded flux core.

Did you verify the numbers as being self shielded wire?

I've seen people get 71t-1 thinking it's the same as 71t-11

Re: How to choose my first roll of Dual Shield?

Just a standard Dual-shield 71t-1 wire will work for your application in my opinion. (note, that's not 71t-11) Either .035" or .045" should work with the power you have available. Check out this chart from Washington Alloy for their wire: http://weldingwire.com/Images/Interior/documentlibr...
